GAS-BURN ER.

SPECIFICATION formingpart of Letters Patent No. 233,609, dated October 26, 1880.

Application filed August 3,1880. (No model.)

' To all whom it may concern Be it known that I, JOSEPH S. FORD, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in GasBuruers, of which the following is a specification.

My invention consists of a pillar solid in its middle portion and having openings at its ends, each of which terminates with a small perforation or side opening leading to the pillar, in combination with the pillar-base and cap, and a tube or shell of larger diameter on its inside than the diameter of the pillar, so as to leave an annular space or chamber around the pillar, in such a manner that as the gas flows through the base it will pass up through the lower end opening and thence through its small perforation into the annular chamber to the upper end of the pillar, and thence through its side perforation into the central opening and through the tip. The base and cap are each provided with an annular recess for the reception of gaskets or packin grin gs upon the ends of the tube, to prevent the leakage of gas in its passage through the chamber to the tip.

So far as relates to the construction of the central pillar above mentioned, it is similar to the main central tube in the patent of F. A. Fisher, dated May 28, 1872,No.127,829; but its combination and arrangement with other parts of the burner are entirely different from those of Fishers tube with the parts connected with it; and the results are also very different in the two inventions. For instance, the upper end of Fishers tube is connected with a cap and a short central tube beneath the tip, which are so constructed and arranged as to cause the gas to fiow upward through an annular chamber between the outer surface of the tip and the inner surface of the cap, and thereby to be highly heated by radiated heat from the tip before it reaches the point of ignition. Fishers burner may be difi'erently adjusted, so as to divert the gas from its upward course around the tip, by causing it to flow downward inside of his main central tube and thence up through the short tube into the tip. The result obtained in either case is different from that with my burner, which being constructed as above described, the gas can only flow from the bore in the upper end of the central pillar directly to the tip.

The accompanying drawing, which makes a part of this specification, is a vertical section of my improved burner.

A represents the base of the burner. B is the pillar; O, the cap; D, a tube formed of glass or other suitable material, which surrounds the pillar; and E is the tip. The main and middle portion of the pillar B is solid. The lower end has a central bore, a, and a side opening, 1), leading therefrom to the periphery of the pillar into the annular chamber Gr, around the latter, for the flow of gas thereto in its ascent through the base A. The upper end of the pillar has a similar central bore, a, and a side opening, 1), leading thereto, for the flow of gas from the upper end of the annular chamber to the tip. I have represented the side openings, 1) and b, at opposite sides of the pillar for the purpose of causing the gas to spread around through the chamber Gr in its passage to the exit-opening b.

The ends of the tube D fit in annular recesses c c ofthe baseA and cap 0, which are provided with packing-rings d 01, whereby tight joints are formed to prevent the leakage of gas.

The pillar and either the base or cap may be formed in a single piece, if desired.

The shell D, instead of being a straight tube, as represented in the drawing, may be of globular or other form, if desired.

I claim as my in ventionl. The pillar B, having a solid middle portion and end bores or openings, a, or, provided with side openings, 1) and b, in combination with the base A, cap 0, and shell D, forming an annular chamber, Gr, around the pillar, substantially in the manner and for the purpose set forth.

'2. The base A and cap 0, having annular recesses c 0, provided with packing-rings cl d, in combination with the shell D, substantially as described, and for the purpose set forth.
